UPDATE: 7:52 p.m. EDT -- White House press secretary Josh Earnest said President Barack Obama will definitely poke fun at Republican presidential candidate Donald Trump during Saturday's White House Correspondents’ Association dinner in Washington.
Speaking to CNN on the red carpet, Earnest promised there would be some jokes about Trump. “It would not be the same if we left him out,” Earnest said.
It wouldn’t be the first time Trump was the butt of jokes at the annual star-studded event. Both Obama and comedian Seth Meyers roasted the billionaire business mogul at the 2011 version of the dinner.
The next day, Trump complained about the barrage of jokes made at his expense. Then a few hours later, Obama announced that Osama bin Laden had been killed by U.S. forces.
Some believe the evening in 2011 led Trump to seek revenge and run for president in 2016.
Earnest, however, isn’t so sure about that. “I don’t think anyone knows exactly why Donald Trump is running for president,” he told CNN with a smile.
Original story:
President Barack Obama will mark his final White House Correspondents' Association dinner on Saturday night, one of many milestones over the next few months signaling his two terms in the White House are coming to a close. But this might be one presidential duty Obama will be glad to leave behind. The annual event known as "nerd prom" brings together journalists and elected officials to listen to the evening's honored guests trash politics and make fun of many of the very same people sitting in the room. Awkward. 
Larry Wilmore, host of "The Nightly Show with Larry Wilmore" on Comedy Central, is expected to roast Washington as the official entertainer at this year's annual dinner. The White House is expected to live-stream the event here.

"Larry's edgy, even provocative, brand of humor means he's certainly up to the task of skewering politicians of all ideological stripes, and we don't expect the nation's news media to escape unscathed, either," Carol Lee, White House correspondent for the Wall Street Journal and president of the White House Correspondents' Association, said in a statement on the group's website. "We are thrilled that Larry has accepted our invitation to be the featured comedian at our annual dinner, which will be the last during the Obama White House."
The nonprofit White House Correspondents’ Association is made up of the reporters, producers, camera operators and other journalists regularly covering the White House. Tickets go to White House correspondents, their editors and special guests of media companies, including senators, cabinet members and celebrities. Proceeds from the $300-a-seat tickets fund scholarships.
Republican front-runner Donald Trump — and his hair, mannerisms and political views — are expected to be everyone's favorite target Saturday night. That may be why he decided to skip the black-tie party.
"The press would say, 'Donald Trump was miserable.' What would I need that for?" Trump said this month, explaining his decision to RSVP "no."
In 2011, Obama got a few laughs at the press dinner after he brought up Trump's constant questioning of where Obama was born.
"No one is prouder to put the birth certificate matter to rest than the Donald," Obama said as Trump looked uncomfortable in his seat in the audience. "And that's because he can then get back to focusing on issues that matter, like did we fake the moon landing? What really happened in Roswell, and where are Biggie and Tupac?”
On the Democratic side, presidential contender Bernie Sanders has said he is going to the dinner. The Vermont senator will rub elbows with singer Aretha Franklin, actor Morgan Freeman, actress Rachel McAdams, model Kendall Jenner, Megyn Kelly from Fox’s “The Kelly File” and Hope Solo, the U.S. women’s soccer goalie, among other luminaries.
